A spy enables a sneaking commander to gain more information about hostile provinces they enter. They are also able to perform some active acts of subterfuge.
A spy in a hostile province does the following:
Reduces scout report inaccuracy to ±10% of the unit's visible, in contrast to a regular scout's 30%1)
Reveals all discovered magic sites
in the province, even without full ownership of the province.
Displays the scales
in the province.
Displays full details of the province's population, income, unrest, resources, supplies, and recruitment points
Additionally, spies can perform the the following actions:
Instil Uprising: Adds d20 (open ended) unrest
to the province2)
Infiltrate: Fails if not used on a nation's capital. Has a 50% chance to succeed3)
. Success updates score graphs for that nation: provinces, forts, and income are always obtained; gem income and research are obtained only if the spy has magic paths, and dominion is only obtained if the spy is a priest.
